Progress in Sodium-Ion Batteries: A Focus on Phosphate-Based Cathodes and Their Interaction With Electrolytes

Abstract

Sodium-ion batteries (SIBs) are attracting interest from both the scientific and commercial sectors due to their unique approach, which contrasts lithium-ion batteries (LIBs). SIBs employ easily accessible and low-cost salt as a primary resource, making them environmentally viable and cost-effective. Researchers have focused on enhancing the performance of cathode, anode materials, and electrolytes in the SIB field, recognizing the urgent need to compete with LIB technology. The paper will concisely address current progress in polymer-based electrolytes and cathode structural materials for SIBs, providing an in-depth review of the developing technology.
